PUNCTURE-IE'BOOF SHIELD FOE, TIRES.

Application filed December 2, 1912. Serial No. 734L545.

To all whom, it may concern Be it known that I, J AMES E. iMCLAUGI-b LIN, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,-have invented certain new and useful Improvements in Puncture-Proof Shields forTires, of which the following is a specification.

provide a simple and effective device which I This invention relatesto puncture proof shields for tires, andhas for its object to may be easily and quickly applied to a a wheel having a resilient tire in such manner as to protect the tire against wear and puncture. With the above obgect in view the device includes rings WlllCll are held by 7 bolts atopposite sides of the wheel. A series of metallic sections are pivotally connected with the said rings.

f together and extend around the periphery of a tire.- These sections have end portions which extend along the opposite sides of the tire, and the inner ends of the said end portions are connected by means of springs The end portions of the sections are provided with openings, and

.the sections are provided upon their outer sides with tractors so disposed as to prevent the wheel fromslipping or skidding in any direction.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure 1 is a side elevation of a wheel with the shield applied; Fig. 2 is a trans- "erse sectional View of part of the same; Fig. 3 is a plan view. of parts of the shield with parts in section.

Corresponding and like parts are referred to inthe following description and indicated in all the views ofthe accompanying drawings by the same reference characters.

The device includes holding rings 1 which are secured at the opposite sides of a wheel indicated at 2 by means of bolts 3 which pass through the rings at the opposite sides of the wheel and also pass through the spaces between the spokes of the wheel These bolts are arranged in pairs, and the members of each pair are located one at each side of one of the spokes and they are in close contact with the same but not connected thereto; therefore the rings 1 are held against turning with relation to the wheel but are free to play laterally thereof.

shield proper is made up of a series of sections i of like dimensions and configuration. These sections are pivotally connected together, and a description of one will answer forall. The sections 1 are approximately U-shaped in edge elevation, and the end portions of the sections are provided with openings 5. Springs 6 connect the end'portions of the sections at with the rings 1. As many about the periphery of the wheel. Each section at is provided upon its outer side with a series of tractors 9 of uniform length, breadth and thickness, and disposed transversely across the vertical plane of the wheel 2, each section is furthermore provided with two sets of tractors 10. The tractors 10are of uniform length, breadth and thickness, each set of tractors 10 are in longitudinal alinement with each other. The two sets of tractors 10 are disposed approximately parallel with the vertical plane of the wheel 2, and a set 10 is located beyond one end of the tractors 9, while the other set is disposed beyond the opposite end. The tractors l0 occur opposite the spaces between the tractors 9, and vice versa. The tractors 9 enable the wheel to stick or cling to a pavement when the wheel is turning in a forward or a rear direction, and the tractors 10 are to prevent the wheel from skidding or sliding sideways.

'Inasmuch as the tractors 10 occur opposite the tractors 9, and vice versa, the wheel they protect the entire tread of the tire, they add no unnecessary weight thereto, and the adjacent edges of adjacent sections diverge from opposite sides of the tread portion thereby, affording space between the adja- .and onthe opposite edge with a pair of hinge lugs, the sections may be used interchangeably sothat, if any section should happen to be broken or bent so as to be incapable of further use, a new section taken I v at random from stock may be substituted therefor, and it is unnecessary to maintain two reserve stocks to meet such emergency. The rings 1 are integral structures so that they will not tendto yield at one point and reduce the holding force exerted upon the the Wheel and bearing against the said shield but will remain concentric with the wheel throughout and, consequently, the springs 6 will be subjected to uniform strain. The rings 1 are disposed outside-the planes of the rim of the wheel so that they are readily accessible for the purpose of fitting the device to a Wheel or removing it therefrom, and the connecting bolts may be easily inserted through the rings.

Having described my invention, what is claimed as new is: I

The combination with a wheel comprising a rim, spokes, and a pneumatic tire, of a shield for said tire consisting of elliptical sections adapted to fit transversely over the tire and each provided at one edge with a single hinge lug and at its opposite edge with a pair of hinge lugs adapted to receive between them the single hinge lug of an adjacent section and each section being provided in its tread portion with outstandin transversely and longitudinally dispose traction lugs and being further provided with openings near its ends and at opposite sides of the said lugs, pintles inserted through the engaging hinge lugs of adjacent sections, integral rings disposed adjacent the sides of the wheel, springs having their outer ends secured to the ends of some of the sections and their inner ends secured,

to said rings, and securing bolts inserted through said rings between the spokes of spokes at opposite sides of the same.

In testimon whereof I aflix my signature in presence 0 two witnesses.
